<span>The proportion of dissolved salts to pure water in the ocean is known as salinity. This is commonly measured in parts per thousand. For example, if the salinity of an ocean is 35 parts per thousand, or ppt, this means that in every kilogram, or 1000 grams, of ocean water, there are 35 grams of salt present. The higher the quantity of parts per thousand, the saltier the water, which also means the higher the salinity.</span>
Answer:
B. Hermit crabs and fish that hide in shells compete with each other for shelter.
Explanation:
Hermit Crabs hides from their predator by hiding in old seashells (e.g those of gastropods) for protection and/or shelter. This is a form of camouflage exhibited by hermit crabs for survival. Now, if peradventure some species also uses the same mechanism for adaptation and survival, vigorous competition will sets in between hermit crabs and those species because the availability of empty shells ata ny given place depends on the relative abundance of gastropods which is crucial for the survival of both organisms from their predators. Sometimes, they may even have to fight or kill a competitor in order to gain access to the shell that favors them.
